java - Android 7.0 不显示多个权限请求

Question

我正在尝试在 Android 7.0 上显示多个权限请求

这段代码在 Android sdk 23 上没有问题。

SDK 24 显示一次请求，如果我触摸允许或拒绝按钮，此代码工作一次并且不显示其他请求。

代码在这里；

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

            if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED) {

                requestPermissions(new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
            }

            if (checkSelfPermission(Manifest.permission.READ_SMS) == PackageManager.PERMISSION_DENIED) {

                requestPermissions(new String[]{Manifest.permission.READ_SMS}, 1);
            }

            if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_DENIED) {
                requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
            }

        }

试试这个

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

            String[] permissions = new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_SMS, Manifest.permission.ACCESS_FINE_LOCATION};
            boolean flag = false;
            for (int i = 0; i < permissions.length; i++) {
                if (checkSelfPermission(permissions[i]) == PackageManager.PERMISSION_DENIED) {
                    flag = true;
                    break;
                }
            }

            if (flag) {
                requestPermissions(permissions, 1);
            }

        }
